Heavy Metals In Particulate Matter In Spokane County, Delaney M. White
Heavy Metals In Particulate Matter In Spokane County, Delaney M. White
2020 Symposium Posters
Heavy metals in particulate matter (e.g., dust) have multiple negative health ramifications for humans including cancer, infertility, and reduced lung function. The Spokane Regional Clean Air Agency (SRCAA) has seven air quality monitoring stations around Spokane County to measure total levels of PM2.5 (particles with a diameter less than 2.5 micrometers) and PM10 (particles with a diameter less than 10 micrometers). For comparison, the width of a human hair is between 50 and 70 micrometers. The objective of this research is to examine the heavy metal composition of the particulate matter including elements such as lead, copper, and zinc. We …
Comparison Of Wetland Restoration Techniques In And Around Turnbull National Wildlife Refuge, Cheney, Wa, Jade S. Clinkenbeard
Comparison Of Wetland Restoration Techniques In And Around Turnbull National Wildlife Refuge, Cheney, Wa, Jade S. Clinkenbeard
EWU Masters Thesis Collection
Throughout the West, wetlands have been drained or filled in for agricultural or urban uses. Staff at Turnbull National Wildlife Refuge (TNWR) in Cheney work with local landowners to restore wetlands through excavation or flooding techniques. Unfortunately, TNWR staff cannot evaluate the wetlands to determine which technique is most successful. This thesis project compared the macroinvertebrate and plant communities and the limnological features of wetlands restored through excavation and flooding with those of unaltered, reference wetlands on TNWR. I hypothesized that the reference wetlands would hold water longest and would have higher plant diversity and macroinvertebrate diversity and abundance than …
